Refilling the coolant system, burping the lines, how-to???

[TheSubaruJunkie]

I just spent the better half of the last 2 days pulling my intake manifold to replace some stupid coolant bypass line that leads from the coolant passage to the manifold.

My radiator and everything is empty, and I need to refill it. I want to know if there is a special procedure in order to refill the coolant as to reduce the chances of air bubbles. And how to burp the lines if I do have any?

I blew 2 coolant lines in 3 days, and i heard if I dont refill the coolant propperly, it could cause problems and lead to blown lines. I'll be damned if im going to do this job again.

Thanks for any help in advance.

It was just last week when my coolant return line from the turbo broke and I had to drain/refill most of the system. Basically put as much coolant in the upper coolant tank as possible, then started the car. Once it started to warm up and the thermostat opened up, the coolant level in the reservoir tank dropped. I kept filling it with fluid until it wouldn't take anymore. Might need to massage the coolant line going into the radiator to get out some large air bubbles. I can tell I've got some small air pockets in mine since I occasionally hear the water trickling sound through the heater core; but those will eventually work themselves out.

Park the car on an incline, if you do not have an incline around your garage, you could jack up the front end, leave the radiator cap open, and let it run until it runs hot, and thermostat opens, keep filling as neccessary.

Also the radiator should have a bleeding valve on the top right corner, loosen, until there are no more air coming out of the valve.

Turbo's don't have a radiator cap to let breath -- only got the coolant condensing tank on top of the block and the coolant overflow tank.
